Patented June 6, 1933 UNITED STATES PATENT OFFICE JAMES c. DAWSON, OF WEBSTER GROVES, MISSOURI, ASSIGNOB r ELMAN. Dawson, 0E WEBSTER GROVES, MISSOURI i CATALOGUE BINDER Application filed June 27,

Among the objects of the invention is the provision of simple means to hold catalogues or folded sheets securely, but detachably between the covers of a book; to provide a 6 binder which may be readily assembled with standard loose leaf covers and which may be attached toa number of sizes of covers without the necessity of carrying catalogue binder parts in stock for each cover size required;

and to provide means for retaining the catalogue which has a minimum number of parts and which avoids the use of latches, retainer rings or slotted locks.

These and other objects of the invention will become apparent from the specification and the appended drawing, in which Fig. 1 is a perspective view ofthe catalogue binder with a broken away section showing the method of retaining the binder plate to the book back;

Fig. 2 is a section through the binder on the line 22 of Fig. 1;

Fig. 3 is a section through the binder on 5 the lines indicated; 2

ferred form of catalogue holding bar;

Figs. 5 and 6 illustrate the end sections of alternative forms of such bars. 7

In its simplest form, the invention comprises a book back with a bar engaging member formed from an upstanding plate at 1 either end of the back. The members are slotted transversely and between them and carried in the slots are anumber of flexible metal bars or wires on which the catalogues or folded sheets are hung.

Essentially also, each end of the bars carries an arm bent or formed substantially at a right-angle to the body portion. On being slipped through the slot, the arm engages the remote face of the plate] and unless the bar is twisted to throw the arm parallel to the slot and simultaneously is shortened by being sprung up from the middle, the bars cannot be disengaged from the slots.

With reference to the Figures 1 to 4 illustrating the preferred form of my. invention, the back 10 is provided with a plurality of lugs 11 in loop form which extend through 5b the fabric covering 12. A plate 13 is pro Fig. 4 is a perspective view of the prea the bars.

ing the plates 20 into the box-like structures 16 shown. In such a case, the retaining slot 17 is cut across the inner face of the box.

The boxes are finished upon all'surfacesas they form the ends of the book.

The. plate 13 may be continuous and bear the boxes 16 on either end, or as shown, two short plates each of sufficient length to en-; gage the lugs at one end of the back, may be used. Where this is the case, the con-' struction has the very great advantage of being usable with many different sizes of books. A thin metal strip 18, forming the catalogue-holding bar, as shown in Fig. 4:, bears a notch 19 cut adjacenteitherend to form the arms 21, 21. The width of the metal in the space 22 between the bottom of the notch and the back of the bar is slightly less than the width of the slot 17. As shown in Fig. 1,

the catalogue 23 is slipped over the bar and the two ends are bent towards each other until the bar is so shortened that it may snap into the slots 17, 17 and be held in place therein. As is illustrated in Fig. 3, the bars may turn in the slot and hence the catalogue may take any of the positions shown without restriction of the motion, or binding or sticking of When the box form of bar retainer is to be used and flat bars are provided, it is advantageous to make the bars but slightly shorter than the distance between the inner opposing faces 3101' the outer walls of the boxes. The notches 19 should then be made wide enough to allow the end 30 of the arm 21 to engage either of the faces 31, depending upon the direction of pull exerted upon the bar. The device may be finished by providing a spring cover plate 24 having inwardly extending hooked flanges 25 which snap over the outer margins of the plate 13.

When the bar is turned parallel with the slot and the catalogue is lifted in the middle, the bar may be readily snapped out of place.

The alternative form shown in Fig. 5 substitutes a Wire 27 for the fiat bar shown.

The arm for holding the'bar in place is pro videdbythe rectangularly bent section 28.

A T-hea-d arm is provided in the form shown on Fig. 6. The extension 32 is welded or otherwise afiixed to the end of the wire 29. In all forms of bars, it is desirable that the metal shall be stiff but capable of being bent to a reasonable degree without permanent deformation from its original shape. The length of the bars being greater than the distance from the outer wall of each box to the inner wall of the other box the bars are prevented from disengagement from the box without fiexure even though they may be turned to bring their arms in register with the slots.

I claim as my invention 1. In a binder in combination, a back, a box-like structure rising from each end of the back and each having an arcuate transverse slot in its inner face, sheet holding bars projecting into the slots each having lateral arms at its ends, each of the arms extending above the slot with which it is associated.
